Quickly activatable structure of gas sensor element

摘要

A gas sensor element which may be employed in measuring the concentration of gas such O2 is provided. The gas sensor element is of a laminated type and designed to introduce gas to be measured into a measurement gas chamber through a diffusion resistor. The measurement gas chamber has a volume of 0.15 mm3 in order to facilitate expelling of the gas remaining within the measurement gas chamber during transition of thermal activation of the gas sensor element.
